INDEX.

To all whom it may concern:

Be it known that I, Fnnmnc G. SHELDON, a citizen of the United States, residing in the borough of Manhattan, city, county, and State'of New York, .have invented certain v of which the following is a specification.

This invention relates to indexes, and aimsto provide certain 1 improvements therein.

The invention is particularly designed for use in connection with religious works wherein certain definite lessons or readings are prescribed periodically by some authoritative body. Such readings are usually chosen with regard to a given line of thought and are but rarely to be found consecutively arranged in the book to which they refer. The reader is hence obliged to refer quickly to separated portions of the work for each days'ilesson.

The object of the present invention is .to provide a temporary index which may be easily arranged in advance for a given lessontor series of lessons, so that the book may be preparedin advance for the work of the succeeding week or month.

The index provided by this invention is so constructed that particular paragraphs or sentences may be indicated thereon, and such marks or in'dicationsmay be expunged so that the index has a practically indefinite life.

The invention also includes means whereby the index pages may be quickly and easily fastened temporarily to the'book without in any way defacing or harming the, latter.'

The invention also includes certain other features of improvement which will be hereinafter more fully described.

Referring to the drawings which illustrate the invention, Figure 1 is a perspective view of a book having therein a series of index sheets constructed according to the present invention, one of such sheets being shown in perspective at the right hand of the figure. Fig. 2 is a plan illustrating one method of fastening the index sheets to the book. Fig. 3 is a perspective view of the top of a book, showing the ends of the series of index sheets. Fig. 4 is a plan showing a. modification.

Referring to the drawings, let A indicate a. book of the character described, being shown as the usual bound volume having a cover a and a series of leaves 6. According Specification of Letters Patent.

Patented Jan. 20,

Application filed February 16, 1912. Serial No. $178,008.

to my invention I provide a series of index sheets B which are preferably nearly the full width and length of the sheets of the book, although they may be of any preferred shape and dimensions, so long as they are capable of carrying the indication marks 7 and the index tabs 0 which extend beyond the edges of the sheets of the book, prefer ably at the front thereof.

In the preferred construction the index sheets B are formed of thin flexible sheets having a surface sufliciently rough to permittheir being marked with a lead pencil or the i like, and preferably being adapted to permit the erasure of the marks without marring the sheet. I have found in practice that celluloid or similar material answers the purpose adl'nirably. Preferably the index sheets are opaque, in which case the user will utilize the side of the sheet which is immediately opposite the printed sheet by placing lead pencil indicating marks opposite the portion of the text which forms the matter to be read. One example of such indicating marks is indicated at d in Fig. 1. Prefen ably also atfisome convenient 'part on the sheetitis usual to indicate the page and lines to be read. Thus in the example shown in Fig. 1 the reading will be on page 563. lines 1 to 8. According to my invention I may also employtransparent sheets constructed of transparent celluloid or other suitable material, in which case the mode of "use may be slightly different, that is to say,

instead of the indicating marks a? thesheet may be provided with. a lead pencil mark surrounding the text appointed for the particular day. This construction is illustrated in Fig. 4-. In such use the sheet will remain over the printed page, and the latter read through the sheet. In the construction shown in Fig. 1 if the text is on opposite pages one side of the sheet B may be utilized for one page and the other side for the opposite page. "W hen the sheets are transparent, however, it is desirable to introduce two guide sheets. one for each page. The index tabs 0 maybe fixed temporarily or permanently to the guide sheets, and may have permanent numbers. in order that the references selected may be consecutively read.

To realize the full advantages of the invention. it is necessary to provide means for temporarily holding the index sheets in place, and these means should be so constructed as to avoi d as much as possible any injury to assays adapted to -be engaged by temporary fastening means, thepreferred form of whieh l'have illustrated. "In this form the are provided with apertures gwhich adapted to receivean'elastic band or her flexiblefastening device. it, the ends '{whicligare provided with means for fasthem" to some convenient part of the book, preferably the covers, C. As'illus- I wire members i at each side of the booktrated, these-fastening means comprise two which are formed at their outer ends with hook portions 71: which are passed through gthe ends of the-elastic band, the bodies of the wire members being located between the printed matter and the covers. The books 7:: are so formed as to pass outside of the book and engage the covers, and also to engage I the flexible band it. At this point there is usually formed a crease .or at least a portion of less thickness than the covers so that the,

'wire members 7' are held fixedly in place.

'Eaeh of the opposite wire members is also preferably provided with an eye portion Z,- the two eye portions being connected together by a thread or small elastic band. In order toasslst in preventing the wire members from twistin The provision of .portant in that it permits the book to be opened, without placing any additional 1 strain upon the sheets, 0

or turning, I preferably form each with adient portion m which lies flat between the covers and printed matter. the elastic band it is imthe band expanding at the place of opening. Furthermore, the band assists in holding all of the index sheets firmly in position between the inner l"edges of the leaves, so that the sheets are not liable to work outwardly in use. In order to prevent displacement in a longitudinal direction the'lugs f extend rearwardly to a point beyond the rear edge of the sheet whereby to engage the top and bottom edges of the sheets as best illustrated in Fig. l.

v In practice the index sheets will be furnished in such number as corresponds to the number of lessons to be read in a definite period, as for instance one week. Each of the sheets may advantageously be provided with permanent numbers on their tabs, and the user will take the appointed list and fix eac .'sheet' in its order at, the proper place within the book, making such temporary marks thereon as will be adjusted in place .and the ends of two 'elastic bands the apertures g in the series of sheets, this indicate definitely the appointed lesson. One pair of the wire retaimng members y will then operation being assisted if desired by a fine hook which is .passed through-the series and 1 engaged with the rubber band so that the latter may be pulled through the apertures. The end of each band isthen engaged by hooks k of the other pair of retaining members, the latter being then adjusted in place. After this is done the reader can without .difiiculty turn consecutively to each reading,

"beginning at tab #1 at the top and working down-one tab at each successive reference.

If desired the tabs may be'printed with the day of the week, or the date, or other suitable matter which will serve to indicate the precise .point at which the book is to' be opened.

The invention provides a construction l which is of great convenience in that it enables a series of reference readings to be indicated atone time without injury to the book or defaccinent of the pages. The record is permanent so long as the sheets remain in their positions, but the latter may be removed and used indefinitely byerasing the indication marks.

lVhile I have described certain embodi ments of the invention, I do not wish to be limited thereto as various changes may be made therein'without departing from the invention. vF or instance, the sheets may be formed of paper or other suitable material and instead of the marks 03, etc., being applied by the user, they may be printed upon the sheets, in which case a new set will be furnished at the beginning of each period. The'mode of attachment to the book may also be considerably varied without departing from the invention.

While the invention has been described in connection with works of a particular character it will be understood that it may be employed in connection with other works which are found useful.
